    Fix getDataSet() for virtual fields that need to requery children.

    Previously, there were two problems with getDataSet() and
    VirtualFields:

    1) If you named the field list, the virtual fields wouldn't be
       included.

    2) If your virtual field needs to requery children, it would show
       incorrect values .

    Both problems are fixed now.
